A mixture of gaseous reactants is put into a cylinder, where a chemical reaction turms them into gaseous products. Thecylinder has a piston that moves in or out. as necessary. to keep a constant pressure on the monure of 1 at. Thecyinder is also submerged in a large insulated water bach. (See sketch at nght)From previous expermenes, ths chemical reaction is known to release 254. of energy.The temperature of the water bath is monitored, and it is determined from this data that 232. k of heat flows into thesystem during the reaction.I the maction enothemicor endethermienduthermDoes the temperature of heater bahdownt1downneitherDoes the piston movein or outretherO does workworkdenOretherDos the gas misture do won, orismo doneon aHom u on is done on ar bv) the gasmure ere v er has the comenumber of significant digits

he following demonstration takes place in a two-step process: rst, solid calcium carbide (CaC2j)reacts with liquid water to produce acetylene gas (C2H2)and aqueous calcium hydroxide. Second the acetylene gas produced is then ignited with a match, causing the combustion reaction of acetylene with oxygen gas to produce gaseous carbon dioxide and gaseous water. Write the balanced equations for each reaction that is occurring, including all phases. If a 100.0gsample of calcium carbide (CaC2)is initially reacted with 50.0gof water, which reactant is limiting? Now imagine that the final gases produced are collected in a large bulkier and allowed to cool to room temperature. Using the information from part b ( l00.0gof Cec2reacting with 50.0gof H2O), how many liters of carbon dioxide gas were produced in the balloon at a pressure of 1.00atm and 25C?
Consider a mixture of air and gasoline vapor in a cylinder with a piston. The original volume is 40. cm3. If the combustion of this mixture releases 950.
